Abstract
A method and apparatus for receiving and recording a digital broadcast program and reproducing a recorded digital broadcast program with time-based trick play features. While recording a broadcast program on a storage medium, the apparatus creates an index file regarding random access points of the program. Receiving a request for a jump or trick play operation given in terms of time, the apparatus detects the time interval between each of the random access points based on the created file. Referring to the time interval, the apparatus determines the position to be reached by the jump and begins playback from the position or determines the number of access points to be skipped for the trick play and begins the requested trick play by skipping random access points by the number, thereby providing a user-friendly interface having time-based trick play features.
